The Soviet Venera program was really fascinating. It is quite impressive that they managed to build landers that survived even a short period on the surface of Venus, let alone return photographs.
> The Soviet Venera program was really fascinating
Reading my uncle’s old tech magazines and sci-fi from the 70’s was fascinating. Eastern European sci fi was all about colonizing Venus and the Venera landers. The way kids in USA are obsessed with Mars, kids in my part of Europe used to be obsessed with Venus before the influx of Western media.
Getting to grow up on the cusp of that vibe shift was cool.

This Kurzgesagt video is equally sci-fi, but of the "potentially possible if we wanted to bankrupt the planet" variety.
On the sci-fi side one notable example is The Land of Crimson Clouds (Страна багровых туч, 1959) by the Strugatsky brothers. Unfortunately, there’s no official English translation that I can find.

A great (if not incredibly satirical and cynical) sci-fi book on Venus colonization is The Space Merchants
If you’re into hard SF I recommend The House of Styx, and The House of Saints by Derek Künsken.

There's a collection of images returned by the various Venera probes (including the surface photos from Venera-9, -10, -13, and -14) restored from tapes of the original transmissions here: http://mentallandscape.com/C_CatalogVenus.htm
Edit: Oop, missed that someone else posted a link to that same site (different page) a while before me. Well, nevertheless.

Probably the coolest space program after Apollo.
The photos, the huge effort involved, and general strangeness of Venus is a great read. Lots of good youtube docs as well.

The Soviets literally beat the US to every single major milestone in the space program, up through the 60's, except for literally landing men on the moon.

US had a couple good milestones with the Mariner program. Mariner 2 was the first Venus flyby in 1962, and Mariner 4 was the first Mars flyby in 1965.

I read about it years ago, I never knew they actually landed on Venus.
That said, I wonder whether with advances in material science and the likes they could build something that lasts longer.
> As this is a lander that was designed to survive passage through the Venus atmosphere, it is possible that it will survive reentry through the Earth atmosphere intact, and impact intact.
I did not consider this outcome at all, but this makes sense. I am hoping the descent mechanism activates and the spacecraft lands intact.

It will not, of course - anything that's inside is long dead, not designed for Earth atmosphere, and it had to be programmed to trigger in the first place.
In fact, the capsule could also burn up on reentry. Sure, it's a Venera-8 double designed to enter Venus' atmosphere at 11.6km/s... but it has extra mass on it (the upper stage never separated so it should look like [1]) and the capsule's CoG doesn't take all that stuff into account, which might cause it to tumble, reenter backwards, or damage it. On the other hand, it's reentering from a really low-energy orbit so it could survive the reentry - but not the impact in case it lands on the ground.
Marco Langbroek, who did the reentry forecast that the linked article is based on, convincingly argues[0] that the bus did separate and reenter separately (in 1981) and what remains in orbit is just the lander. There are several independent pieces of evidence that are consistent with this; the orbital decay pattern, the radar cross section and optical telescope observations all point to only the lander itself remaining.
See also his blog[1] for an up-to-date reentry forecast.
The descent mechanism would be built for the much denser Venusian atmosphere. On Earth, it may not slow the thing down enough.

I think it's a safe bet that any descent mechanism designed for the thick atmosphere of Venus is not going to function the same way on Earth.

That would be pretty cool indeed. My only concern is that the craft probably doesn't have any attitude control, so it may enter backwards or tumbling, which may limit the effectiveness of the heatshield on the probe. Even so, surely large pieces of it will make it back home intact.
voidUpdate 4 hours ago [-]
If it is the same as other venera probes, it is designed so that aerodynamic forces will stabilise it into a heatshield-forward attitude
This reminded me of space junk and what the heck are we going to do with it?? There's not enough money behind cleaning it up to make it even feasible. There are some interesting magnetic ideas, but overall it seems like the concept of space junk is just here to stay.

Is there somewhere I can read about why the Trans Venus injection burn failed?
js2 4 hours ago [-]
> 1972 March 31 - . 04:02 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC31. LV Family: R-7. Launch Vehicle: Molniya 8K78M. FAILURE: The escape stage Block L's engine cut off 125 seconds after ignition due to timer failure.. Failed Stage: U.
According to Wikipedia, the stage timer was set incorrectly so the injection burn cut out early.

That would be more likely for outer system probes, where even simple radio isotope heaters could be very useful.
For Venus it is unlikely to need anything like that, as the expected flight duration was much shorter (quite important for not very durable Soviet electronics) and main issue would be actually cooling.
